Long-term outcomes of surgical treatment for paediatric acute mastoiditis: the role of mastoidectomy.

Purpose: Despite the declining incidence of acute mastoiditis (AM) due to antibiotics, complications persist, necessitating surgical intervention in severe cases. Recent studies suggest conservative treatments, avoiding mastoidectomy, show high recovery rates. However, this trend raises concerns about severe complications, prolonged treatment, increased antibiotic use, and declining surgical skills.

Exploration of different electrode types inserted in a 3D model of a patient with incomplete partition type III inner ear malformation.

Background: Incomplete partition type III (IP III) represents a rare malformation of the inner ear, posing challenges during cochlear implantation due to inevitable cerebrospinal fluid (CSF) leaks and the potential misplacement of electrodes within the internal auditory canal (IAC). Despite the absence of a consensus on electrode selection, literature suggests both straight and perimodiolar electrodes as viable options for proper insertion. Limited implantation series contribute to the ambiguity in electrode choice.

Audiometric and Vestibular Function after Classic and Reverse Stapedotomy.

Besides classical stapedotomy, reverse stapedotomy has been used for many years in the management of otosclerosis. Our study aims to investigate whether reversing the surgical steps in stapedotomy impacts vestibular function and hearing improvement. A cohort of 123 patients underwent either classic or reverse stapedotomy procedures utilizing a fiber-optic argon laser.

Distribution of Neck Metastases and Survival in Patients with Breast Carcinoma.

Purpose: Neck metastases in breast carcinoma are relatively rare and patients show poor survival rates. A controversy exists over whether neck metastases can be treated as distant or loco-regional metastases. The literature concerning the distribution of metastases in the neck is lacking, as well as data about whether metastases in the higher neck regions cause poorer survival than those in the supraclavicular fossa.

Highly Protein Repellent and Antiadhesive Polysaccharide Biomaterial Coating for Urinary Catheter Applications.

Engineering functional biomaterials surfaces that resist biofilm formation triggered by unspecific protein adsorption is a key challenge, and these biosurfaces hold a huge potential in implant-associated infection. Herein, we report a water-based facile approach to install carboxylated-hyaluronic acid and sulfated-fucoidan on cationically tethered polydimethylsiloxane (PDMS) implant. We showed that these hydrophilic, charged, polysaccharide-based biosurfaces/biocoatings provide long-term stability, no adsorption of proteins (albumin and fibrinogen), similar to zwitterionic polymers, and enhanced resistance to plasma deposition and growth of pathogen.
